PSP

Work on PSP Linux has started at PSP Linux. Check it out, especially if you're a developer. It should be pretty easy to get it running, since the PSP uses a memory stick and can load applications on there, but for now nobody knows for sure. The U.S. release will jumpstart the development process, thats March 24, 2005.

Short bit of specs:

PSP CPU CORE

Two MIPS R4000 32bit Cores

128bit Bus

1 - 333MHz @ 1.2V

Main Memory: 8MB(eDRAM) (**Changed to 32MB, 4MB embedded in May 2004)

Bus Bandwidth: 2.6GB/sec

I-Cache, D-Cache

FPU, VFPU (Vector Unit) @ 2.6GFlops

3D-CG Extended Instructions

The description should be taken with a grain of salt. The R4000 is a 1991 vintage 64-bit processor for high-end workstations and processors, not an embeddable core and so hardly what would be used for a battery powered device. Aside other processors of the same vintage such as the R4600 would be faster and less power-hungry.
